DNFSB’s Summers ends board tenure, extending agency’s loss of quorum
Lee
Summers
The Defense Nuclear Facilities Safety Board, the independent agency responsible for ensuring that Department of Energy facilities are protective of public health and safety, announced that the board’s acting chairman, Thomas Summers, has concluded his service with the agency, having completed his second term as a board member on October 18.
Summers’ departure leaves Patricia Lee, who joined the DNFSB after being confirmed by the Senate in July 2024, as the board’s only remaining member and acting chair. Lee’s DNFSB board term ends in October 2027.

The first calculation of energy exchange between electrons and the radiation field by inverse Compton and Compton recoil was reported by Hurwitz in Los Alamos Reports LA-301 (1945) and LA-553 (1946). These reports have not been generally known; even in 1950, Bethe called attention to their neglect. Yet, they predated Kompaneets’s widely cited 1957 paper and original 1950 report. “Comptonization” is important in many astronomical objects as well as in fusion energy. I make a very brief comparison with Kompaneets’s work and present Hurwitz’s reports as appendixes.
